Displaying Logged On ClientsLocate this document in the navigation structure

Procedure

You can display a list of currently logged on systems by choosing Start of the navigation path Goto Next navigation step Logged on systems End of the navigation path.

The following values are displayed for each system that is logged on:

  • LU Name: With CPIC connections via TCP/IP, this field describes the host on which the partner program is running or is to run.

    Note

    The term “logical unit” is a term borrowed from SNA and describes a logical node in an SNA network. The remote partner program is intended to run on this node.

  • TP Name: Name of the transaction program or the name of the program that was started by the gateway.

  • System Type. The following values are permitted:

    • NORMAL_CLIENT: Normal client (external program)

    • LOCAL_R3: Local SAP System

    • REMOTE_GATEWAY: Connection to remote gateway

    • FROM_REMOTE_GATEWAY: Connection from a remote gateway

    • REGISTER_TP: Registered transaction program

  • Host Name: Name of host client is running on

  • Host address: All TCP/IP names on the host. If there are several network cards then there may be several entries here. Usually 5 alternative host names are supported.

  • Last Request: Time of last activity

  • Connection Status: Connection status to a client or another gateway at TCP/IP level. The default value is Connection OK.

    In the following cases connections are highlighted in color in the gateway monitor.

    • Connections with status Connection Pending (handshake while opening the connection) are colored orange

    • If the data packets could not be fully written in the network connections, the connection is colored green. If this status lasts for a while, it indicates network problems, or the partner program cannot read any data from the network, because it is busy with other tasks that take time (for example, BRBACKUP).

  • Reg. Status: Status of a registered RFC server program. Following statuses are possible:

    • Logged on: The program is logged on, but is not accepting any requests

    • Waiting: The program is waiting for calls from the system

    • Running: The program is processing a request from the system
